We are converting a summer cottage to a year round home. Water for the house comes from a well about 125 feet away. The copper pipes leave the well at a depth of about 2 1/2 to 3 feet deep. As they approach the house which has no basement and is on a concrete slab the pipes are now about 20 inches deep in the ground when they are 7 feet from the building. As the reach the building the pipes a down about 9 inchs. WE live in the Northeast, Long Island to be exact.

Our question is this: Should we leave everything as isand just hope for a mild winter and perhaps let the water drip on real cold spells? Or should we start digging and lower the pipe and if so how far do we need to go back towards the well to be safe?

Thanks for any advice and also if there is any NEW process out there that could be used in lieu of the digging?
